To wliom 'iz' may concern:

Be it, known that le? lonnm citizen oi: the United States, and :i resident. of the borough of liyoiniseingl` neer the city of Re; ding, in the county ot' Berks and State of @enneylvzinizn have invented eei'tztin new and ueeini l'niproi'eineiiir-i in rniding-ltlachinee.,A of which the followings; in e epm-inmition.

invention eintee to braiding; nineliines and my pertieulm' ooje iS to provide :in improved eoiieiruetion 'which witl enable o port only of the carriere that are jointly e111- 'plojy'ed in ordinary braiding, to be separately operated at, intervals upon a disconnected Section oit the eoniinon rites-Way The invention iS fully dee-w'ibed in ronneetion ii'itli the aceoinpnnyinb drawing and the novel features are speenliy pointed out in the cliiinie.

Fig. 41 indicates a -tiorni of braid which may be made iin-on tige improved machine indieatedj The carrier race-Yay indie-ated in tlie top plate l of tine machine illustrated,-ditl'ers from that of :in ordinary breider in the arrangement of :i portion thereof in ssiieli vinonner ne to permit of a Secten of said race-Way being disconnected, 'wien desired, sees to serve :is e sectional course upon Winch a part,

These results :are etf'eeed :is Shown by means of the vertically niouitlile clut; rod Q() (see Fig: 3) which unies, tirs a firm 2l provided with e pin 2Q- giiidedin a' aperture in the, bottoni plate :ind adepte to enter i hole lil in Seid toothed port, lz and second, un arm 25 carrying i rotfxtebl Gluten sleeve 26 having n pin 2? guided in :in aperture 28 in the gear l5 und adopted to enter enother hole @l in said part l5, The clutch rod 2O is raised and lon/*ered dsired by means oipn bell-crank 3() 2)7 which is pifoied to :i brat-inet` 31 and oper ated by pattern n'iet-,lnmisnn through connect ing; wires 32, 33; e suitable spring-preeeed holding means 3G being employed in well {nown manner es indicated 'o yieleingly refrein the nell-crank in setu position. Tne Switch l() is ISiniilmidy operated by the ptittern mechanism through connecting wires et?, attached to n double arm 422 on the switch siiaitfifi?, and retained in Setl position by eiiniiar lioldinoj means. The blind Switch il, which is automatically 'urned by the. corriere, coperaies with the Swieli 10 in well known manner to connect; or disconneet the sectional course raee-eireles 2, 3.

The Simple form of pattern mechanism shown comprises two 1i-Wheels 5), lined to n shaft 52 arranged gef-e witl'i shaft 17 already referred to; enid Wi ls be- (bv. Flin.' S3' -at determined intervals, as

`vill be readily ont erstood.

The simple torm of braid shown in Fig. is pr duced upon theparticular torni of my improved machine herein specilically de scribed, in manner readily understood hy reference to Fig. l. lloro the switches l0, ll are represented as set. so that the race-oircles 2, 3 are disconnected from the adjoining` i'aceriicles 5, si, l, el to form a sectional race-way upon which the carriers 60, 60, 60 indicated will be retained in operation While the othercarriers(30,601,60a upon the main portion of the race\vay, are at rest; snch sectional operation being adapted to produce the narrow-braided loops indicated at Gl, Fig. 4t. lt will be understood that during such operation the clutch-rod 2O is in raised position, as indicated in Figs. 2 and 3, so as to disengage the gear l5 from the separably rotatable part l5 and lock the latter by means of the locking pin 22 to the hedplate la. W hen however the switch l0 and clutch rod 20 are reversely moved by the pattern mechanism, it will be readily seen that the sectional race-circles 2, 3 will be thrown intoconnection with the main racecircles 5, 4, il, .el through the linking grooves 6, 6, and the sectional drive-gears 13, 13 into cooperative connection with the train of gears l5, 14, l2, l2, l, sothat all the carriers will be traversed upon the Whole racef Way to produce the full Width of braid interveningbetween the loops 51, 6l. The length of this narrowed or loop portions of braid (in the present case a soutaohe) is ydetermined by the interval of time allowed to, elapse before reversing the switch and clutch to reconnect the sectional course with the main course -for renewal of the normal operation of the machine, Which interval may be varied as desired by the pattern mechanism.

Vihet l claim iszl. in' a braiding machine, a race-Way, a

series of copeinttA carriers and drive mechanism therefor, switch mechanism tor disconnectingl tit intervals a section of said race-way with certain of said carriers there` on, and controlling means for said drivemechanism whereby the latter carriers only are made to operate during disconnection of said section. f

2. ln a braidinrf;` machine, a race-way, a series of jointly operated carriers and drive mechanism therefor, switch mechanism for disconnectilrgl at intervals ansection of said raconay with certain of said carriers thereon, controlling means for said drive mechanism whereby the latter carriers only are made to operate during disconnection of said section, and means for simultaneously operating said switch mechanism and controlling` means.

ln a braiding n'iachine, a race-Way, a series of jointly operated carriers and drive mechanism therefor, switch mechanism for disconnecting at intervals a section of said race-way with certain of said carriers thereon, and clutch mechanism whereby the operation or carriers outside of said section is stopped upon disconnection of said section and restarted upon reconnection of the same'.

ln a braiding machine, a race-Way, a series of jointly operated carriers and drive mechanism therefor, switch mechanism for disconnectin at intervals a section of said race-Way Wit certain of said carriers thereon, clutch mechanism whereby the operation of carriers outside of said disconnected section is stopped without stopping the operation ot' the carriers on said section, and pattern mechanism controlling the operation of said switch and clutch mechanisms.

ln testimony whereof, I affix my signature, in the presence of tivo Witnesses. Y ROBERT C. RAHM.
